Re: uspsa approved 9mm production load?
Friday's on the mark in terms of common 9x19 production loads.
By the way, I used the major pf as an example of the risk/reward process that experienced IPSC/USPSA competitors use.
Experience from shooting 10-12 Nationals over the years and Area matches. Your ammo typically chronos differently at matches than what you might measure at your home range. Makes sense, right? Many variables: altitude, humidity, distance to skyscreens, etc.
We're fortunate in CO to have Greg "Chronoman" chrono many of our local, big matches. So we get verification from his set up which is often used at Nationals. That being said, don't get too risky with Production loads making the 125 pf. I have seen GMs/Ms go home at Natls when they went sub-minor. Maybe not a big deal at a big, local match (like a state championship) but a very big deal when you've spent $1000+ on travel, lodging, match fees at a Level 2 or higher match that you've traveled great distance to.
The perceived recoil of a 126 pf load vs. a 132 pf load is slight at best.
